We reduced our mobile checkout from 16 to 10 fields in a two-week test (Shopify with address autocomplete), which bumped conversion 7.4% and cut address errors by about 30%. If you’ve made phone or account creation optional to keep the flow clean, did delivery accuracy or post-purchase support take a hit, or did the simpler interface hold up?
But same setup (Shopify + autocomplete); kept phone optional and saw no delivery dip by only requiring it for intl/courier and prompting apt/unit when keywords hit. > the flow clean, did delivery accuracy or post-purchase support take a hit, or did — support got lighter with a WISMO autoresponder + tracking webhooks, but fraud checks were slightly slower without phone. Are most misses domestic or cross‑border?
Tried nudging phone opt-in on the thank‑you page with “Get SMS updates”? We moved account creation to post‑purchase via a one‑click magic link and run USPS Address Validation when creating labels to catch missing units, keeping phone optional without delivery hiccups: https://www.usps.com/business/web-tools-apis/address-information-api.htm. We only require phone on high‑risk baskets (AVS mismatch + high AOV), otherwise the simpler flow holds up and doesn’t feel like a tax form.
